Silvology is the general science of forest ecosystems, without the usual division between Man and Nature. This systematic treatment of forests intends to integrate and harmonize existing approaches with the help of systems modeling in a hierarchy of close system levels, according to criteria of biological architecture, biomass production and species composition. Scientists and practitioners will appreciate this synoptic treatment of forests and their ecology, allowing the balance of holistic and reductionist viewpoints, and the placement of phenomena and techniques. Topics covered include: - introduction of the methods, - sections on forest organisms, - a special chapter on trees, - eco-units, i.e. forest ecosystems developing after some zero-event like fire, storm or waterlogging, - silvatic mosaics built by the eco-units of different size, architecture and species composition, - a summary of silvological rules determining system's behaviour at every level, e.g. fragmentation and fusion, transfer of functions, irreversibility and process oscillation.
Proceedings of a conference on Tropical Forests: Botanical Dynamics, Speciation and Diversity held at the University of Aarhus, Denmark, August 8*ba10, 1988.The increasing rate of destruction of the world's tropical forests gives grave cause for concern on several counts. In conservative terms, species are being lost at an incredible rate, many before they have even been described. In scientific terms, habitats, communities, and unique systems are lost before they can be studied and used to broaden our understanding of ecological processes in general.The meeting on which this book is based aimed to address two basic needs: to describe some of the marvellous biological treasures of tropical forests and to learn what they can tellus about processes in ecology, and to alert us all once again to the disaster which is overtaking this rich and varied environment.
No matter what forests are used for, forest managers have to deal with interactions between individual trees and between trees and other forest organisms. To understand these interactions, long-term monitoring of spontaneous forest development is necessary. A complete monitoring system has been developed including a computer package for analysis of long-term observation of forest dynamics. The system's name, "SILVI-STAR", is an acronym of SILVIgenesis and Single-tree Three-dimensional Architecture. A method of nested plot data collection on forest architecture and plant species composition has been developed out for monitoring purposes.
Horticultural Reviews present state-of-the-art reviews on topics in horticultural sciences. The emphasis is on applied topics including the production of fruits, vegetables, nut crops, and ornamental plants of commercial importance. It is a serial that appears in the form of one hardbound volume per year.
In recent years, tropical forests have received more attention and have been the subject of greater environmental concern than any other kind of vegetation. There is an increasing public awareness of the importance of these forests, not only as a diminishing source of countless products used by mankind, nor for their effects on soil stabilization and climate, but as unrivalled sources of what today we call biodiversity. Threats to the continued existence of the forests represent threats to tens of thousands of species of organisms, both plants and animals. It is all the more surprising, therefore, that there have been no major scientific accounts published in recent years since the classic h...
Drawing on research from biodiversity experts around the world, this book reflects the diversity of forest types and forest issues that concern forest scientists. Coverage ranges from savannah and tropical rainforests to the ancient oak forests of Poland; issues explored include the effects of logging, management practices, forest dynamics and climate change on forest structure and biodiversity. Here is a useful overview of current science, for researchers and educators alike.
Research on dendrimers has exploded in the last 15 years, moving from the establishment of synthetic methodologies, particularly in the early years up to the end of nineties, towards sophisticated and wide-ranging applications. Dendrimers play an important role in many different areas, spanning from basic synthetic approaches to artificial photosynthesis, to medicine, to catalysis. The great potential of dendrimers is well-recognized by the hundreds of papers in the field and the increasing number of patents, and stimulated developments in other areas of knowledge, including new characterization techniques. However, some basic principles and methods still continue to give a unity to the fiel...
